Polygon: wrap & unwrap POL

Convert POL ⇄ WPOL 1:1 with the official WPOL contract. Use your connected wallet or process a whole list of wallets in one run.

Switch network

What is WPOL?

WPOL is POL packaged as a standard token. DEX pools, lending markets, NFT marketplaces and many smart contracts can only handle tokens, not the native coin, so they use WPOL. The WPOL contract holds every deposited POL and mints exactly the same amount of WPOL; unwrapping burns it and returns the POL. Nothing else is involved — no price, no slippage, no counterparty.

Why use this tool

  • Canonical contracts only — the same WPOL address that DEX routers use, verified on-chain.
  • Every transaction is simulated first; the network fee is shown before you sign.
  • “Max” keeps enough POL for gas, so a wallet is never left unable to move.
  • Bulk mode: wrap or unwrap in many wallets at once (entire balance, a percentage or a fixed amount), keys never leave your browser.
  • No service fee — only network gas.

FAQ

Does wrapping change the value of my POL?

No. 1 POL = 1 WPOL, always. The contract holds the POL and gives it back 1:1 when you unwrap.

When do I need WPOL?

When a protocol works only with tokens: adding liquidity, some DEX trades, lending, NFT bids or a bot that trades WPOL pairs.

How much does it cost?

Only the network fee of one contract call. ChainTx charges nothing for wrapping or unwrapping.

Is bulk mode safe?

Private keys are processed only in your browser tab to sign each wallet’s own transaction and are never sent to our servers. For everyday use, the connected-wallet mode needs no keys at all.
